[Aflatoxin B1 in flours (author's transl)]

Inadequate storage conditions may cause growth of fungi on foodstuffs. Most well known fungi are Aspergillus species, which produce a number of toxins known as aflatoxins, destructive to human health. Several health organisations consider these aflatoxins and their metabolites as toxic and cancerogenic and state limitations on their amount in foodstuffs. In ninety three flour samples screened for aflatoxins, three were found to contain aflatoxin B1 over the limits or very close to it.
